A new class of pyrrolo[1,4]benzodiazepine (PBD) analogues featuring a pyrazolo[4,3-e]pyrrolo[1,2-a][1,4]diazepinone ring system has been designed and synthesized. These compounds, 2a-o, are characterized by the substitution of the aromatic A ring, characteristic of the PBDs, with a disubstituted pyrazole ring bearing alkyl and benzyl substituents at N6 or N7 and alkyl or carbomethoxy substituents at
设计并合成了以吡唑并[4,3-e]吡咯并[1,2-a] [1,4]二氮杂庚酮环体系为特征的新型吡咯并[1,4]苯并二氮杂(PBD)类似物。这些化合物2a-o的特征在于用具有N 6或N 7上的烷基和苄基取代基和在C 8上的烷基或碳甲氧基取代基的二取代吡唑环取代PBD的特征的芳族A环。生物学评估表明,化合物2a,b,fi具有明显的体外细胞毒活性。
